我在網路上找解法，試完後不是沒效果就是跟我問題沒直接的關係(很多都是說 php 的)

這是我的配置(以訪問 tomcat 練習)

最一開始的默認配置長這樣

server {
        listen 80 default_server;
        listen [::]:80 default_server;

        root /var/www/html;

        index index.html index.htm index.nginx-debian.html;

        server_name _;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.

               #  這行我自己加的 #
                proxy_pass http://127.0.0.1:8080;

                try_files $uri $uri/ =404;
        }
}

我另外在下面寫一個

server {
       listen 9001;
       listen [::]:9001;

       server_name 192.168.0.102;

       location ~ /edu/ {
               proxy_pass http://127.0.0.1:8000;
       }
}

然後如果直接從 8080 去訪問可以正常顯示，換做以從 9001 就不行了
請問這樣子該怎麼解決? 找不到為什麼
